func main() {
	r := gin.Default()
	r.LoadHTMLFiles("index.tmpl") //解析模板

	r.GET("/index", func(c *gin.Context) {

		//方法1：使用map
		// data := map[string]interface{}{
		// 	"name":    "张三",
		// 	"message": "是个人才。",
		// 	"age":     18,
		// }
		//方法2 go定义好的gin.H(相对于map)
		data := gin.H{"name": "张三", "message": "是个人才。", "age": 18}
		c.JSON(http.StatusOK, data)

	})

	r.GET("/indexstruct", func(c *gin.Context) {
